The problem of interaction of two rough surfaces is traditional and topical nowadays. Various deterministic models of contact of real surfaces are known. However, experimental data indicate the substantial stochastic nature of the microrelief. The article considers the attempt to examine the contact between two surfaces, the profilograms of which are designed by some stationary stochastic processes. This examination is helpful in clarifying the real picture of the contact and the analytical structure of the function of approachment. The technique of definition of approachnment of surfaces and of loads on microasperity are presented. They could be used to solve the problems of the strength assesment of the contact point of the interacting surfaces. Knowledge of the functions of approachment permits to determine the number of microprotrusions which are in contact and, therefore, to assess their strength in the frameworks of the accepted fatigue wear modelReferences
